TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.

[bpratl]

I presently have OSF V1.1.0 installed and running but would like to flash the motor and my 860C with V20.1C.3.
What should I expect the major difference and the biggest improvement to be ?
Is the displayed data the same? Thanks.

Hello.
I’ve been riding with 20.1c3 NEW for quite some time and it has been the best firmware ever!
One thing that I noticed is that voltage readings are off about one volt.
Is there a way to correct voltage readings?
I am using 860c display.

Hi,

One of my bikes running v20.1C.2 now and then shows the brake error on booting. When this happens at home I can easily flash the stock option byte file which resolves the problem, but it has also happened when on the road

I’m not sure what’s causing this issue. Can it be a bad controller? Or am I flashing the wrong option byte file?

Kind regards,
Dennis.

Hi Dears:
I am using TSDZ2-v20.1C.1-VLCD6.
Now I set only＂battery current＂ data display on VLCD6.
That let me monitor battery current when I am riding at hill.



But I found the ODO meter won't increase anymore, even enable or disable "Odometer compensation".
Is my wrong configure setting?

If you want to see the current continue (time to display =0), it is logical you can't measure odo and speed anymore, because the time is always set to measure current, so there is no time left to capture and process the speed pulses.
This is because there is only one display value (normally speed) which is shared, that is why you must enter a certain display time.
The "always on" possibility is usefull for diagnostic measurements.
If you want more display options you must choose another display like 860C.

Yes, I understand, thanx for your reply

Bug with "Hybrid" mode?
I'm using Emmebrusa's OSF version 20.1C with my original VLCD6 display in eMTB mode. I recently changed the default to Hybrid mode and liked the extra power it gives. Having swooped down a slope and begun to climb I resumed pedalling at a high cadence. The motor lost power but continued to run with no response to pedal pressure. In a panic I forced the bike to stop, stalling the motor. This blew the controller. Forunately my BMS detected a short and protected my battery.
Whist waiting for a new controller from PSWpower I fitted my spare motor also programmed with the same OSF.
A friend said there was a new OSF version "with safety features", 20.1.1C. So I uploaded this new version thinking this fault had been sorted and set the default back to Hybrid mode. After a couple of weeks of normal riding I again resumed pedalling in too low a gear and high cadence and the fault recurred. I went round in circles in the middle of a field and managed to jump off and raise the back wheel and then lay the bike down. This enabled me to disconnect the battery. After reconnecting (and selecting the safe eMTB mode!) the motor works fine.
I've used the OSF for about 2 years in eMTB with no problems and love it. However now this has happened twice I'm sure there is a bug in Hybrid mode. If like me you don't have a kill switch then I suggest you don't use Hybrid mode until someone figures out the problem.
The fault occurs when resuming pedalling at a high cadence, suddenly making the motor run fast, and this only happens in Hybrid mode.

I on 20.1C3New already broke 2 blue gears, it breaks them at the moment of sudden pressure going uphill, I have no idea why, I came back to 0.8.

[mbrusa]

The broken blue gear can be caused by too aggressive settings.
The parameters to pay attention to are:
Motor acceleration (in all modes).
Startup boost (in power mode).
Torque assist levels (in hybrid mode).
In my tests I tried to exaggerate with these parameters, there were no problems with the blue gear, but I had to be very light on the pedals.
With 860C and conservative settings, since April I have done 1500km (500 with v20.1C and 1000 with v20.1C.3) without any problems.

The problem reported by Hangman for the version with stock display is different.
The motor that gets stuck in acceleration without control and without pushing on the pedals, is a rare but known problem.
It happened in all previous versions, mine and marcoq's.
But only in stock display versions, I have never had any reports of this problem with the LCD3 and 860C, yet the motor control code is the same.
I thought I had remedied with v20.1C.1, unfortunately this is not the case, there is also a report on GitHub to confirm that the problem has remained.
I still haven't figured out what the cause may be, but in the new version I've been trying for 2 months, I've added a function that stops the motor when there is no more control. It will then be necessary to turn the display off and on again.
It does not eliminate the problem, but it can avoid danger and damage.
Before I release it, I want to try a couple more weeks.

I have only just noticed a small bug with v20.1C.3-LCD3 firmware in that the brake sensor icon on the display does not show upon brake activation, the brake sensors however perform as expected and kill the motor instantly so no issues there.

I have only just upgraded my bike with brake sensors to the latest version from the previous version v20.1C-LCD3 which did not have the issue.

I now have two KT-LCD3 displays with v20.1C.3-LCD3 flashed on to them and they both fail to display the brake sensor icon when the brakes are applied so I don’t think it can be a hardware fault. I haven’t seen this bug reported before (and there is nothing on GitHub), can anyone else running v20.1C.3-LCD3 with brake sensors confirm? Thanks.

Hello. I changed the torque sensor to a new one. I now have the display of the sensor value, when you give the full weight, it decreases. Although you can ride. Is it incomprehensible to the bee?

[Charlie Whiskey]

The voltage indication on my system running C3 new is 0.8V too hard according to my calibrated multimeter.

I've already done the battery resistance test and set the corresponding value so that is not the issue. Going through the manual there doesn't seem to be anything else that impacts this. Have I missed something? Is there anything else I can do to resolve this?

[mbrusa]

On 860C there is no voltage calibration, I'll try to add it to the next version.

I have never heard of the adc torque value that decreases with max weight.
It is probably a hardware calibration problem.

It was true. But today it became normal. Apparently the system has somehow adjusted itself.

Installed osf on my dads bike(v20.1C.2) my dad was on the trail and the battery was 62% and suddenly battery % jumped to 81%
any idea why?

[Nfer]

Why are you using v20.1C.2?

[razm]

Hi !

Thank you for all the great work done here! I was trying to compile version TSDZ2-v20.1C.1-VLCD5-VLCD6-XH18 on my MAC running on big Sur 11.5.2. When executing

Code: Select all

make -f Makefile_windows

i get an error on the ebike_app.c compile step - see below:

Code: Select all

sdcc -c -I../common/STM8S_StdPeriph_Lib/inc -I../common -I. -I../ -mstm8 -Ddouble=float --std-c99 --nolospre  --out-fmt-ihx --debug  -oebike_app.c ebike_app.c
make: *** [ebike_app.rel] Illegal instruction: 4

Did anyone hit this issue before? Any tips on a fix for it?

Thank you !

[razm]

I found the issue! and managed to flash the firmware - it rocks! so much better than the original! Great job!

It is linked to a bug in the Java configurator - If any of the fields where speed needs to be entered (i.e. Basic Settings /Max speed off-road mode , Assistance Setting / walk assist speed & Street speed limit) gets empty the configurator throws and error and I guess the resulting config.h gets corrupted and the error below shows at compile time.

To avoid the error make sure speed input fields should never be empty - eg when you want to change the offroad speed limit from 25 to 30 - first add 30 to he input filed and delete 25 afterwards (25->2530->30).

Hope this helps somebody at some moment in time. I'll also drop a note on github .

I flashed version v20.1C.1

The motor keeps running without pedaling, as if the throttle is working, but I did not install the throttle.
This is the second time, this time I am sure it is wrong.
Fortunately, it can be stopped by the VLCD6 power button.

Hello again!

Now that I have managed to have the firmware flashed and I am very happy with it I am looking for the next upgrade. I have just ordered a new SW102 and the necessary cables. While waiting for the delivery I was checking the where are all the latest firmware and Otaupdates and was not clear wich repositories have what. Can somebody please help with locations/repositories for following?

-latest TSDZ2 firmware
- initial firmware for SW102
- latest OTAupdate for SW102

Thank you!

Thank you so much mbrusa, I am waiting for that function. Your firmware is the best! I am still running C3NEW and it's my best bike ever.
